31:(group-V, especially phosphorus and arsenic) and one or more other elements. Although this group of compounds has been recognized since 1995, interest in these compounds increased dramatically after the publication of the superconducting properties of LaOFeP and LaOFeAs which were discovered in 2006 and 2008. In these experiments the oxide was partly replaced by fluoride.

Many of the oxypnictides show a layered structure. For example, LaFePO with layers of LaO and FeP. This structure is similar to that of ZrCuSiAs, which is now the parent structure for most of the oxypnictide.
